Swiss Nokia N9 Cyan 16 GB - not getting the update (AGAIN!).

Does anybody have an idea why Swiss phones never get any OTA updates?

Nokia care said my provider (o2 Germany) was blocking the update, but there's still no OTA update when I remove the SIM card.
Also, a friend of mine got an Austrian modell which always receives all updates with the same provider.

I've got PR1.1 in January (!) via NSU because I couldn't wait for the OTA update any longer...
